Construction Technology of Prestressed Vierendeel Truss Aqueduct
The No.39 aqueduct of Water Diversion Project from Datong River to Huangshui River in the Qing-hai Province is located in Kayang of Lanlongkou town.The total length of the aqueduct is 178m and consists of 5 spans.The project adopts the scheme of integral casting of the hollow truss and the construction of the trough body after the tensioning of each span is completed.4 spans are through vierendeel trusses with single-span-length 40m,and the aqueduct body is located above the lower chord of the truss,with a total of 5 spans.The thesis mainly discusses the materials required for the project,the installation method of the formwork and scaffolding,the concrete construction plan,and the prestressing process.At the same time,the thesis carries out safety calculations on the stability of the formwork construction and demonstrates the feasibility of the project.
